What's a good, simple business WP Theme?(maybe not SO simple,,pls,, read on)

Hey Warriors,,

I'm putting together a site, and as always, I come here to get you guyses advice, tips and pointers on how to get something done in the best possible way.

I trust you fellers.

Anyway,, I'm building a (Mobile Website niche) based site. I want to be able to put video on it,, of course text,, be able to capture emails,, have some sort of way for customers to purchase and pay on the site,, etc.

Also,, I wanna have a basecamp type "section" where outsourcers can log in and get project details and leave info as well and share files. Yes,, it's a lot,, sorry,, go big or go home is my motto.

So,, anybody got anything anywhere NEAR what I'm talking about? Or is this more of a plug-in type thing I'm looking to do. Any and all suggestions will be appreciated.

I love you all,

Robert X

p.s. And if anyone can SHOW me a good site set up,, in the Mobile Niche area,, by all means,, give me the link. I'm looking for something I can see to get an idea of where I want to go ( I do have a good idea in my head)
